YES When the paper is fed from the ADU: Is the ADU exit sensor working? (Perform the input check: 03-[FAX]OFF/[8]/[G]) ↓→ NO → 1) Check if the connector of the ADU exit sensor is disconnected. 2) Check if either of the connectors CN211 or CN213 on the ADU board is disconnected. 3) Check if the connector CN340 on the LGC board is disconnected. 4) Check if the connector pins are disconnected or the harnesses are open circuited. 5) Check if the conductor patterns on the ADU board and LGC board are short circuited or open circuited. 6) Replace the ADU exit sensor. 7) Replace the ADU board. 8) Replace the LGC board. YES Is the registration sensor working? (Perform the input check: 03-[FAX]ON/[9]/[E]) ↓→ NO → 1) Check if the connector of the registration sensor is disconnected. 2) Check if the connector CN338 on the LGC board is disconnected. 3) Check if the connector pins are disconnected or the harnesses are open circuited. 4) Check if the conductor pattern on the LGC board is short circuited or open circuited. 5) Replace the registration sensor. 6) Replace the LGC board. YES Check the rollers. Replace them if they are worn out. When the paper is fed from any of the lower drawer, PFP or LCF: Open the jam access cover. Is there any paper in front of the upper drawer feed sensor? → YES → Remove the paper. NO Are the upper/lower drawer feed sensors working? (Perform the input check: 03-[FAX]ON/[3]/[H], /[3]/[G]) ↓→ NO → 1) Check if the connectors of the upper/lower drawer feed sensors are disconnected. 2) Check if the connector CN338 on the LGC board is disconnected. 3) Check if the connector pins are disconnected or the harnesses are open circuited. 4) Check if the conductor pattern on the LGC board is short circuited or open circuited. 5) Replace the upper/lower drawer feed sensors. 6) Replace the LGC board. YES Check the rollers. Replace them if they are worn out.

• Code: EB60

• Code: F090
• Description: SRAM abnormality on the SYS board
• Remedy: (1) Turn the power OFF and start up the Setting Mode (08). (2) When the message “SRAM ERROR DOES IT INITIALIZE?” is displayed on the LCD, press the [INITIALIZE] button. (SRAM is cleared.) (3) Turn the power OFF and then back ON. If the error is not recovered, replace the SYS board.

• Code: F091
• Description: NVRAM abnormality on the SYS board
• Remedy: (1) Turn the power OFF and start up the Setting Mode (08). (2) When the message “NVRAM ERROR DOES IT INITIALIZE?” is displayed on the LCD, press the [INTERRUPT] or [INITIALIZE] button. (NVRAM is initialized.) (3) Perform the panel calibration (08-692). Note: When the NVRAM is initialized, the scanner and image processing related adjustments are also initialized. Readjust them after the NVRAM initialization. (4) Turn the power OFF and then back ON. If the error is not recovered, replace the NVRAM on the SYS board.
